You put $10 on red. The wheel is still spinning when the picture freezes. By the time you get back to the table, the dealer is taking bets for the next spin. Open your game history and look for the spin you bet on. Under bet365’s UK disconnection rules, an accepted live roulette bet settles on the result if you had no further decision to make.

Now picture the same interruption at a blackjack table. You have a seven and a five, and the hit and stand buttons disappear before you choose. The hand can carry on without you. Which action the game takes depends on the rules at that table, and a different casino may handle the same two cards differently.
